SPECIFICATION forming part of Letters Patent No. 451,026, dated April 28, 1891. Application filed July 31, 1890. Serial No. 360.498- (No model.)

T0 on whom it may concern:

Be it known that I, GEORGE W. GLARK,-a

citizen of the United States of America, residing at Volga, in the county of Clayton and State of Iowa, have invented certain new and useful Improvements in Cattle-Stanchions; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification. 4

This invention relates to improvements in cattle-stanchions.

The object of the invention is to provide a cattle-stanchion which is pivotally secured at its upper and lower ends toa frame by means of slotted connections, so that said stanchion can move back and forth; also, to provide a stanchion with an automatic latch device, whereby when the animal contacts with the same one of the bars of the stanchion will swing upon the pivot to secure the animal between the vertical bars thereof. 4

The invention also provides novel means for automatically locking the movable member of the stanchion.

The invention, having these objects in view, besides the production of a cheap and efficient device for the purpose intended, consists in the construction and combination of the parts, as will be hereinafter fully set forth", and particularly pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure 1 is a front View of a cattle-stanchion constructed in accordance with my invention, the same being shown closed in fulllines and open in dotted lines, the upper portion being in section to better illustrate the construction. Fig. 2 is a plan view of the stanchion,showing it partly turned upon its pivots. Fig. 3 is a detailperspective view showing the pivotal connection of the stanchion with its frame.

A refers to the frame erected at the front end of the stall or forming a part of the sam e, and it consists of vertical posts A and A rigidly connected to each other at their upper ends by a transverse piece a, to which is secured a block a, havinga depending headed pivot-pin b, a corresponding fixed pivot-pin Z) being secured to the floor of the stall or to a transverse base-piece, when such is provided.

The stanchion is made up of the parts 0, D, and E, which are rigidly connected to each other, and to which is secured a movable member F and auxiliary devices, as will be hereinafter more fully referred to. The vertical upright C of the stanchion has rigidly secured to its lower end a transverse block E, one end of which is bifurcated vertically for the reception of the lower end of the bar F, which is pivot-ally secured thereto, and this block may also be provided with side extensions, to which are secured a slotted plate e, having upturned ends through which pass the securing means, the head of the pin Z) lying Within said slot. This will permit the stanchion to have at its base a lateral movement upon the fixed pin 1). The upper part D, which is fixed to the upright O, is provided with a similar plate inverted, as shown at f,and through the slot of the samepasses the pin (2. The outer end of the block D is bifurcated or slotted, as shown at d, and carries a pivoted latch G, havinga transverse pin g, which rests upon the upper edges of the bifurcated portion of the block D, so as to limit the downward movement of the latch, while upward movement is limited by the beveled outer end thereof engaging with a transverse pin g. This latch G holds the pivoted memberFparallel with the fixed member 0 when closed.

The under side of the block D is provided with a spring catch or plate H, upon the under side of which rides the end of a rod 2', carried by the pivoted member F, and to the lower end of this rod 11 is secured a weighted lever 01, one end of which projects beyond the front face of the bar F, so that when the said bar is moved outwardly or swung to one side the rod 2' will engage with the end of the plate H to hold the parts extended or the stanchion open. The bar F on its outer edge near its upper portion is provided with a projecting pin 7:, havingan opening through which passes a rod Z, attached to a weighted bell-crank lever M, pivoted within a slot formed in the member F, the lower end of said bell-crank lever carrying an arm m, with a knob formed thereon which passes through a plate n attached to the stanchion, so that by pulling upon the lever M having the knob, the upper end of the weighted bell-crank lever will be elevated and will cause the rod l to abut against the front portion of the catch G, so as to raise the same out of engagement with the upper end of the pivoted bar F, and by further drawing upon the arm m the stanchion will be moved upon its lower pivot and held at an angle with the member 0. \Vhen the upper end of the member F is moved outwardly, the pin will abut against the post or upright A and prevent the stanchion tilting upon its pivots.

0 refers to a cross-bar, and said cross-bar is pivotally secured to the upright O, and is provided with a connecting-bar p, which extends downwardly from a point near the pivot and engages with an arm P, secured rigidly to the bar F, a stop-pin 19 being provided for preventing the crossbar swinging beyond the member 0 of the stanchion. When the pivoted member F is thrown at an angle, as shown in dotted lines, Fig. 1, the cross-bar 0 will be in a nearly horizontal position,and when an animal is driven into the stall he will pass his head through the upper portion of the stanchion and lower the same to reach the food usually placed in the trough or upon the floor, and by so doing will depress the cross-bar O, and the end thereof contacting with the projecting end i of the weighted latch will depress the same and release the rod 2' out of engagement with the end plate H.

The spring R, secured to the lower block E and bearing against the loop secured to the member F, will cause the pivoted member of the stanchion to close or assume a vertical position, thereby securing the animal between the bars 0 and F, the latch G falling to be in engagement with the upper end of said pivoted bar. When it is desired to release the animal, it is only necessary to draw upon the arm m having the knob when the device will be reset.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, in a cattle-stanchion, of the blocks D and E, rigidly connected by a vertical bar, the same being supported within a frame by slotted plates and headed pins, a pivoted bar F, secured to the lower block, the upper end moving within a slot in the upper block, which is provided with a gravitycatch, abell-crank lever weighted at one end and connected to an arm having a knob, the projecting end of said bell-crank lever carrying a rod which passes through a pin for elevating the latch, substantially as shown,

and for the purpose set forth.

2. The combination, in a cattle-stanchion, of the blocks D and E, rigidly secured to the vertical members 0, the upper block being provided with a latch which engages with the' upper end of the pivoted bar F, said bar also carrying a rod 2' and weighted arm connected therewith, a bell-crank lever carrying a rod Zfor elevating the free end of the latch G, and a cross-bar adapted to engage with the weighted arm 1', so as to release the pivoted member and permit the same to be automatically locked, substantially as set forth.

3. The combination, in a cattle-stanchion, of the pivoted spring-actuated member F, a releasing-catch consisting of a bar I, connected to a weighted arm having a projecting end i, said pivoted cross-bar being adapted to engage therewith, so that when the same is depressed the upper end of the pivoted stanchion will move automatically inwardly, substantially as shown, and for the purpose set forth.

4. The combination, in a cattle-stanchion constructed substantially as shown, of a pivoted cross-bar 0, connected to the fixed bar 0 and connected by a rod 1) to an arm P, carried by the pivoted member, and means for moving the upper end of the pivoted member inwardly when the cross-bar is depressed, for the purpose set forth.

5. In combination with a stanchion, a frame having upper and lower headed pins 1) and b, slotted strips secured to the blocks D and E, with which said pins engage, a spring carried by the lower block, so as to engage with the pivoted bar of the stanchion, and a latch carried by the upper block, so as to engage with the upper end of the movable bar and hold the same locked, substantially as set forth.

6. The combination, in a cattle-stanchion constructed substantially as shown and provided with a spring-actuated pivoted bar F, of means, substantially as shown, for holding the same either open or closed, a pivoted cross-bar O, connecting-rod p, and arm P, a catch-rod 2', provided with means for throwing the same upwardly in engagement with the notch on the upper block, the same having a projecting portion, with which the end of the cross-bar engages when depressed, so as to release said catch-bar, and an arm also carried by the pivoted bar of the stanchion, which is adapted to be raised by elevating the gravity-catch out of engagement with the upper end of the pivoted side bar of the stanchion, substantially as set forth.

In testimony whereof I affix mysignature in presence of two witnesses.
